I received this Pokémon as a shiny Type: Null from Gladion at the Æther Paradise on my Sun version.
This Pokémon was soft-reset manually: this means that no tools (such as e.g. PKMN-NTR bots) were involved in the hunt for this Pokémon.
I started soft-resetting on the 19th of February 2017 and I finally received the shiny Type: Null on the 26th of February 2017 at 12:40 p.m after soft-resetting for 7 days.
The Shiny Charm does not affect Type: Null's shininess in any way, shape, or form and the odds of encountering a shiny Pokémon without any modifying factors are 1/4096 in Generation 6 and 7 games.
Synchronizers however work in 100% of the cases when soft-resetting Type: Null.
On the 1st of July 2017 I figured that this Pokémon was still capable of improvement and I decided to re-train a UT copy of the Pokémon in question.
The reason behind this decision is that my notorious perfectionist tendencies made me want to have a version without a hyper-trained Special Attack IV stat.
I finished the Alola Ribbon Master™ for this version on the 2nd of July 2017.
The kotobuki is an auspicious chimera from Japanese mythology whose body contains parts from all twelve animals of the zodiac.
The Silvally is nicknameable, which means that I can and will customize the nickname or revert the nickname back to the original name ❝Silvally❞ upon request.
